CVE-2026-45382

libde265 prior to v1.0.19 contains a heap-buffer-overflow read in decode_slice_unit_tiles caused by unvalidated PPS tile geometry (ctbAddrRS computed from PPS colBd/rowBd without ensuring it fits CtbAddrRStoTS.size() == sps->PicSizeInCtbsY). A malformed PPS that passes set_derived_values but e...

libde265 is an open source implementation of the h.265 video codec. Prior to version 1.0.19, decodercontext::decodesliceunittiles libde265/decctx.cc:920 reads pps.CtbAddrRStoTSctbAddrRS at line 966 where ctbAddrRS = ctbY ctbsWidth + ctbX is computed from PPS-supplied colBd/rowBd arrays without...
